A method and apparatus for calculating the actuation control of a hydraulic sub-system of a braking system in order to reduce noises associated with the hydraulics is presented. Input signals and measured/determined characteristics are utilized to calculate a value of a drive time for an inlet valve

A method and apparatus for calculating the actuation control of a hydraulic sub-system of a braking system in order to reduce noises associated with the hydraulics is presented. Input signals and measured/determined characteristics are utilized to calculate a value of a drive time for an inlet valve, a value of a pulse width modulator output, a duration of a current signal reduction time and a pulse width modulator value associated with the current signal reduction time, all of which determine actuation control of the hydraulic sub-system.

The support structure of claim 1, wherein when said support structure is in said swing configuration, said support structure is an open top swing. 10. The support device of claim 1, further comprising: a highchair support rotation lock located on said support structure to prevent rotation of said support structure with respect to said swing arm, said highchair support rotation lock including a lock extension located on one of said swing arm and said support structure and a lock surface located on the other of said swing arm and said support structure, said lock surface configured to mate with said lock extension to prevent rotation of said support structure with respect to said swing arm. 11. A support device, comprising: a frame having a lower portion and an upper portion; a swing arm rotatable with respect to said frame and having a longitudinal axis with a proximal portion and a distal portion, said proximal portion located adjacent said upper portion of said frame and said distal portion being disposed below said upper portion; a support structure including a seat that is located on said distal portion of said swing arm and displaceable relative to said swing arm between an upright configuration and a reclined configuration; and a rotation lock located on said support structure to prevent rotation of said support structure with respect to said swing arm; wherein said rotation lock includes a lock extension located on one of said swing arm and said support structure and a lock surface located on the other of said swing arm and said support structure, said lock surface configured to mate with said lock extension to permit rotation of said support structure between said upright and reclined configurations. 12. The support device of claim 11, wherein said lock extension is configured as a rail and said mating surface is configured as a channel such that said support structure can be guided along said swing arm via said rail and channel to said highchair configuration. 13. A support device, comprising: a frame having a lower portion, an upper portion, and a swing motor; a swing arm rotatable with respect to said frame and having a longitudinal axis with a proximal portion and a distal portion, said proximal portion located adjacent said upper portion of said frame; and a support structure rotatable relative to said swing arm, located on said swing arm and movable between a first and second position of said swing arm so as to configure said support device between a highchair configuration and a swing configuration. 14. A support device, comprising: a frame including first and second support legs extending downwardly from a hub portion; a swing arm rotatably mounted on, and extending downwardly from said hub portion such that said swing arm can rotate about said hub portion; a support structure including a seat that is disposed below said hub portion and is rotatable relative to said swing arm to allow said support structure to be configurable between a highchair configuration and a swing configuration; and a swing lock located on one of said frame, said swing arm and said support structure, said swing lock configured to couple said frame to one of said swing arm and said support structure to selectively prevent rotation of said swing arm with respect to said frame. 15. The support device of claim 14, wherein said swing arm is a rigid swing arm, said swing arm includes a first position and a second position longitudinally offset from said first position, and wherein said support structure is located at said first position when in said highchair configuration, and said support structure is located at said second position when in said swing configuration. 16. The support device of claim 14, wherein said predetermine
